Sam Borros did the installation of the A&A Supercharger himself. After a couple of months with the supercharger he sent us a message: “Hi guys, I’ve had my Corvette supercharged for about 4000 miles now, and still can’t stop smiling every time I get on the gas. What a fantastic product you guys make!!!”

Ron took a little time off and drove from Tempe, Arizona, to A&A Corvette in Oxnard, California.  He did not want to do the installation himself and had looked around his area for a installation shop and finally decided to bring the car to A&A Corvette.  He showed up on a Tuesday and Jesse and James got to work on his 2007 Victory Red Corvette. Friday afternoon Ron was ready to go with his new found power, which included:

• A&A Corvette Performance Supercharger Kit
• Vortech V-2 T-Trim Supercharger making 8lbs of boost
• 60 lb./hr. Fuel Injectors
• Kenne Bell Boost-A-Pump
• A&A Custom Supercharger Cam 218-232 117LSA
• Dual valve springs
• Dewitts radiator
• Autometer dual gauge pod
• Autometer Boost and Fuel Pressure gauges
• 540 RWHP
• 490 RWTQ

Ron spent most of Saturday cruising around Ventura County to make sure the car would not have any issues. On Sunday, he headed back to Phoenix. Ron says: “The car ran perfect with no issues. The only problem is with the driver trying to keep everything under control. When passing trucks and any other slow moving traffic it is quite easy just press the go peddle.”

Vortech superchargers operate on fundamental and proven turbomachinery principles, first described by Euler’s turbomachinery equation developed in the 18th Century. This principle states that the work imparted to a fluid by an impeller is related to the change in angular momentum of the fluid. From these humble beginnings, the centrifugal compressor has evolved and found its way to becoming the most efficient and reliable means for delivering charge air at high pressures. Vortech has seized upon these known performance advantages and has developed its line of centrifugal superchargers to a performance level that clearly establishes Vortech as the performance and technology leader in aftermarket supercharging.

Vortech Cutaway

ADVANCED COMPRESSOR STAGE

Here’s where the rubber meets the road. Vortech’s compressor stages are highly evolved, thoroughly tested designs, resulting from more than 15 years of experience and thousands of production supercharger units. A simple visual examination clearly shows the difference. All Vortech compressors incorporate sophisticated impeller designs, coupled to a vaneless diffuser, with a progressive scroll, or volute exit stage. Impellers employ advanced aerodynamic features such as optimized inducer blading, splitters, and in some cases, exit rake and backsweep… all depending on the particular pressure/flow objectives. Rather than a simple change of blower speed to effect different “models”, each Vortech supercharger is optimized aerodynamically so that best performance is attained for a specific vehicle application.
In order to effectively take advantage of impeller work, flow must be efficiently diffused so that pressure rise can be generated with minimal losses. Unfortunately, a simple “cut-and-paste” won’t work. Instead, the diffuser is optimally matched to the impeller flow physics, with many iterations tested and verified until maximum efficiency is achieved with each supercharger design. Finally, a matched volute effectively collects and diffuses further, resulting in additional pressure rise. The result? Isentropic efficiencies as high as 80%! In fact, all Vortech compressors achieve at least 72% peak efficiency, with better than 65% efficiency achieved over a majority of design flow range (surge to choke).

COMPONENTRY

Vortech componentry has garnered a reputation for its “best in class” execution. Blower casing components are cast from A356 aircraft-spec aluminum alloy treated to T-6 condition. Modern CNC production cells ensure that part tolerances are held into the “tenths” - to, and in many cases beyond aircraft tolerances.

IMPELLER

The heart of any centrifugal supercharger is the impeller. Our piece is investment cast from an extremely strong but light-weight proprietary aluminum alloy (similar to that used in turbochargers). This special heat treated material is used because of its stability and enhanced properties at the high operating temperatures …which may reach 400°F under extreme conditions. At this temperature, the Vortech impeller is up to 36% stronger than even 7075, a common structural aluminum material used by others. The investment cast process secures close dimensional tolerance and excellent surface finish. Of course, 100% CNC machining ensures exact tolerances. And finally, multi-plane dynamic balancing to better than ISO G0.4 tolerances delivers smooth operation. The historical use of these same procedures in building aircraft turbomachinery components for the most demanding applications proves its durability.

DRIVE GEARS

Drive gears are manufactured from 8620 and 9310 carburized billet alloy steels. These premium grade materials possess exceptional strength and durability, with enhanced core toughness properties. The gear teeth are CNC precision ground. The internal step-up drive system is engineered to reliably support impeller speeds exceeding 70,000 rpm.

BEARINGS

Vortech bearings are ultra-high precision (ABEC 7/ABEC 9) pieces that are made in the USA. Most are custom manufactured to our specifications. Aircraft quality is truly an understatement here, since these bearings experience speeds as much as twice that of a jet engine. The supercharger has proven to be one of the most effective means for obtaining increased power from an internal combustion engine without having to make major engine modifications. This is accomplished by compressing combustion air before it enters the cylinders, which increases density. This results in improved cylinder filling, allowing more air and fuel to be burned in the combustion cycle, with dramatic increases in torque and horsepower.

Why would you want to supercharge your C5 or C6 Corvette instead of other engine modifications? The A&A Supercharger kit brings you dramatic increases in power while not degrading everyday drivability or highway gas mileage! The system utilizes a large blow off valve that remains open at cruise and light throttle. This, essentially, allows the supercharger to “freewheel” under normal conditions, reducing parasitic loss to less than that of an alternator.

A naturally aspirated engine would require higher compression, a very aggressive camshaft, high flow cylinder heads with heavy duty valvetrain, exhaust headers with free flowing exhaust, larger throttle body, high flow intake manifold, free flowing air filter housing and duct, etc. Most of these parts are NOT emissions legal. The price of these components alone is higher than a supercharger system. The labor to install these is also much higher. Then there are the inherent problems brought to the vehicle by such a build. A large camshaft all but ruins everyday drivability AND gas mileage. Driving in traffic becomes a very trying experience. A stick shift car will buck and surge and an automatic car will be hard to hold back because of the increased idle speed required. Low speed torque is reduced with an aggressive camshaft which will require lower differential gearing and a high speed stall torque converter (automatic cars) to make up for it. This further degrades drivability and gas mileage. With all the components required for a high performance naturally aspirated car, the degradation in drivability and gas mileage, the total inability of the vehicle to pass emissions tests and the added expenditure, the vehicle would STILL have up to 100HP less than a stock Corvette with one of our standard systems bolted on.

Average increase TO THE REAR WHEELS is approximately 175 RWHP! No other modification, in this price range, even comes close.
